Fuel for internal-combustion engines



we re MILTON G. WHITAKER, 0F NEW'YORK, N. Y., ASSIGNOR TO U. S. INDUSTRIAL ALCOHOL C0,, A CORPORATION OF WEST VIRGINIA.

FUEL FOR INTERNAL COMEBUSTION ENGINES.

No Drawing.

To all whom it may concern:

Be it known that I, MILTON C. WHITAKER, a citizen of the United States, residin at New York city, in the county of New ork and State of New York, have invented a" certain new and useful Improvement in Fuel for Internal Combustion Engines, of which the following is a specification.

My inventlon relates particularly to fuels designed to be used in aeroplane motors, but is applicable for use in internal combustion motors of all kinds used in flying or for other purposes. I

The object of my invention is to provide a fuel which is especially adapted for use in aeroplanes, although it is also applicable for use in internal combustion engines in general.

used in aeroplane motors shall have great dependability, inasmuch as any uncertainty in the'operation ofthe aeroplane, by reason of variability in the character of the fuel or failure of the fuel to perform its intended work, may bring about disastrous consequences.

For this reason, is desirable to avoid to provide fuels of the above character containing alcohol and, a petroleum hydrocarbon blended by the use of benzol, and the constituents of which are chosen in such a manner as to obviate any tendency of the henzol to crystallize out .or the constituents to separate out within the range of atmospheric temperatures to which aeroplane motors are subjected at the varying altitudes in which aeroplanes operate.

Further objects of my invention will appear from the detailed description thereof contained hereinafter.

While my invention is capable of being carried out in different ways, for the purpose of illustration I shall describe only certain ways of carrying out the same herein.

Specification of Letters Patent.

It is necessary that fuels which are to be Patented June 20, 1922.

Application filed November 12, 1919. Serial No; 837,397.

For example, a fuel made in accordance 40%, although I have obtained thebest results by the specific composition above given.

The ethyl alcohol in the above composition may be the ordinary alcohol having a. strength of 95%, but I may, if desired, use an alcohol having a greater. strength, or even absolutealcohol.

By the use of the ethyl acetate I avoid the necessity of using alcohol having a greater strength than 95%, as the ethyl acetate will prevent the benzolfrom crystalizing out at very low temperatures.

Instead ofv the ethyl alcohol, however, I may use methyl alcohol or butylalcohol, and instead of the benzol I may use toluol, and instead of the ethyl acetate I may use other esters such for example as methyl butyrate,

ethyl butyrate, methyl acetate, butyl acetate or amyl acetate, all of which are volatile esters. or still other esters could be used as for example, castor oil.

Aeroplane fuels made in the manner dey ternal combustion engines generally, whether usedfor operating aeroplanes or not.

While I have described my invention above in detail, I wish it to'be understood matic hydrocarbon, and at least 20% of ethyl acetate. J

3. A fuel comprising an alcohol, benzol, and at least 20% of ethyl acetate.

v 4. A fuel comprising ethyl alcohol, benzol, and at least 20% of ethyl acetate.

5. A fuel comprising "from 35% to 50% of an alcohol, from 25% to 35% of an aromatic hydrocarbon, and from to 40% of an ester.

6. A fuel comprising from 35% to 50% of ethyl alcohol, from to of benzol, and from 20% to of ethyl acetate.

In testimony that I claim the foregoing, 10 I have hereunto set my hand this 6th day of November, 1919.

, MILTON C. WHITAKER.
